FASTER FOR IPAPER-BOX `MACHINES.

Application field April 14, 1913.

To all whom it may concern Be it known that I, EUGENE H. TAYLOR, a citizen of the United States, residing at Hyde Park, county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Pasters for Paper-Box Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to machines for the manufacture of paper boxes, and particib larly to machines of the class known as box ending or end-setting machines which are employed to attach blanks to ends or bottoms in the manufacture of boxes.

The device shown herein is especially designed to be used in a machine for applying false bottoms to boxes in the manufacture of so-ealled extension edge boxes. One machine of this kind is shown in United States Letters Patent No. 827,762, granted `to me August 7, 1906, but the device embodying my invention is believed to be applicable to paper box machines of other types.

My present invention has for its object to provide new and` improved mechanism for the application of paste to the proper portions of the blanks before they are fed forward to the pressing mechanism, to be incorporated into the finished box.

The paster embodyingmy present invention is particularly intended for use in a wide range of sizes of boxes, a relatively small number of extra parts being required. The paster members are also so constructed as to have a maximum rigidity and at the same time to be easily and quickly adjustable for changes in size of the blanks to be operated upon. The paster is so constructed that it may be set up and adjusted to the size required on a bench and after it has been so adjusted and the parts secured in place, it may be put bodilyin place in the machine.

The invention will be fully understood from the following` description, taken in connection with the accompanying drawings, and the novel features thereof are pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a top plan view of a paster embodying .my invention, the paster being extended to its largest limit. Fig. 2 is a front elevation of the paster shown in Fig. 1 partly in section. Fig. 3 is a 4section on line 3--3 Fig. 1 looking in the di- Specication of Letters Patent.

rection of the arrows some parts being broken away. Fig. L is an end and Fig. 5 a front elevation of the end paster supporting member 15. Fig. 6 is a plan view showing the pastor closed to its smallest size. Fig. 7 is a top plan view of my improved paster provided with pastor members of a size adapted for use in the manufacture of a medium size box. Fig. 8 is a detail show- 'ing another form of paster members for use in connection with the smallest sizes of boxes which can be made with the use of the pastel' shown and described herein.

For convenience in the following description, I have referred to my entire device as apaster. I have also referred to the series of members which actually apply the paste to the box blank as pasters, but it will be understood from the context whether the entire mechanism or the separate members are referred to. I have also referred to the pasters as front and back pasters and end pasters, these pasters being respectively those at the top, bottom, and sides of Fig. 1.

Referring now to the drawings, and more particularly to Fig. 1, there is indicated at A in dotted lines the carrier track of a paper box machine for the purpose of indicating the position of the pastor with relation to the other parts of the machine. At 11 and 12, see also Fig. 2, are shown two.down wardly projecting rods upon which the paster is supported, and by means of which it is given its vertical reciprocating motion to cause the same to dip in the paste and then apply the paste taken up by the pasters to the box blank. It will be understood that these rods are carried by the sides of the hopper and movable with them in the well known manner as may be seen by examination of my Patent No. 827,762, hereinbefore referred to.

At 13, is shown a webbed cross-bar upon which the various pasters are supported. Said cross bar 13 is provided with two lateral flanges or edges 14:, which slide in cori responding ways formed in the end-pastel A supporting member 15, so that, when the hopper sides (not shown) are moved to adjust the hopper for the different sizes of blanks, the paster operating rods 11 and 12 y will be free to move relatively to the bar 13. Each of the end pasters 17 and 1S is provided with a dove-tail slide 19, see Fig. 2, movable in a corresponding groove in the end-paster-supporting members 15.

The y end pasters 17 and 18 are therefore movable longitudinally and are secured in any desired position by means of the set screw 22 which clamps the dove-tail slide 19 against the corresponding portions of the endpaster-supporting member 15. The grooved member 21 which is part of the end-pastersupporting member 15 is provided with a boss 23 (see F ig. 4) in which are two holes 24 and These holes 24 and are engaged bytwo Y pins 26 and 27 respectively which proj ect horizontally from a collar 28 secured to the bottom end of each of the pastel' operating rods 12 by means of a pin An adjusting and tightening screw 30 passes through the said collar 28 and its end engages the boss 23 on the end-psister-supporting member 15. It will therefore be seen that by changing the position of the adjusting screw 30 the entire paster is held from lateral movement (i. e. longitudinally of the cross-barv 13) or the screws may be employed for a slight lateral adjustment of the entire paster.

The front and back pasters may be made in a single piece, or in a series of pieces according to the length of the line of paste necessary to be applied to the boX blank. In Figs. 1 and 2 the front and back pasters are shown as being each constructed in three parts 31, 32 and 33, there being spaces left between the proximate ends of the members so that when the pasters rise they will not collide with the carrier track A. rI`he pasters 31 and 33 are each supported on an intermediate cross bar 34 which runs from the front to back in the machine. The intermediate cross-bar 34 is supported on the cross bar 13 and secured to it in the following manner: The top of the cross-bar 13 is grooved and the underside of the intermediate cross-bar 34 is provided with a corresponding groove which is transverse of the cross-bar 34. A key or spline 60 is inserted in the two grooves as shown in Figs. 2 and 3 and is secured in some suitable manner as by a driving lit. Two clamping pieces 36 and 37 are provided one end of each of which bears on the underside of the lateral flange 14 of the cross-bar 13 and the other end of which bears against the web 38 formed on the underside of the intermediate paster bar 34. Two screws 39 and 40 hold the clamping pieces firmly against the respective members.

At the ends of the bar 34 when in the position shown in Fig. 1 are secured the pasters 31. These pasters 31 are each carried on a supporting member 41 resting on the upper side of the bar 34 and being provided with a groove in which is a key 42 engaging a longitudinal groove in the upper surface of the bar 34. The paster supporting members 41 are therefore slidable longitudinally of the bar 34 and are secured in place by means of a clamp 43 and set screw 44. The space between the proximate ends of the pasters 31 and 33 is partially filled by a paster 32 secured to a third or middle cross bar 46 which runs from the front to back of the machine parallel with the bars 34. The bar 46 is preferably integral with or a part of the cross bar 13. The paster 32 is slidable on the bar 46 and is secured thereto in a manner similar to that described in connection with the pasters 31 and 33.

From the foregoing it will be seen that when a bo-X of smaller size than that shown in Fig. 1 is to be manufactured, the pasters are moved together by means of the mechanism previously described. If required, the intermediate pasters 31 and 33 may be removed together with the cross-bars 34. In this case, it may be desirable to substitute for the end pasters 17 and 18 other end pasters 50 and 51, and 52 and 53 respectively (see Figs. 7 and 8) provided with U-shaped pasters made in one or more parts. These end pasters 50 and 51 may be made adjustable longitudinally, that is, from front to back of the machine, if desired, as shown in Fig. 8. In this way by substituting pasters the machine may be used for the manufacture of a wide range ofsizes of boxes and with a relatively small number of specially c constructed pasters. 'Ihe pasters are easily and quickly adjusted as described and are lirmlv supported on the respective cross bars so that a rigid construction capable of use in a machine of rapid operation is produced.

Also, as the pasters are set and adjusted to the required size before they are put in place in the machine, they may be adjusted with great accuracy and much more quickly than is possible where the adjustment must `be made in the machine.

In practice the parts of the paster are adjusted for the size of the blank to be operated upon before the paster is put into the machine and the parts are secured together by the various clamping screws at this time. In practice, also a gage or other suitable device is employed for setting the paster to the size required. After the parts have been adjusted and secured together by thel clamping screws, the paster is placed in the machinel and the ends of the pairs of pins 26 and 27 are inserted in the corresponding holes in the boss 23 on the end paster supporting members 15 and then the paster operat- 1.
